Allegedly because of restrictive measures from the United States supply of materials which went from America and Japan of the Photo stopped: Sergey Developers of the Russian passenger MS-21 liner faced Bobyliov/TASS a serious problem: because of sanctions of the USA supply of materials for a composite wing from America and Japan is stopped. About it Kommersant was told sources in the aircraft manufacturing industry. According to one of them, "the remained stock of composites is calculated on six planes". The serial release of MS-21 has to begin in 2020. It for three years later originally planned date. If to create production of composite analogs in Russia, then the liner will leave in a series for about five more years later. At the same time the decision to refuse a composite wing in favor of metal does not make sense at all, the aviation expert, Candidate of Technical Sciences, the ex-designer of Developmental bureau Dry Vadim Lukashevich says: Vadim Lukashevich the aviation expert, Candidate of Technical Sciences, the ex-designer of Developmental bureau Dry "Now civil aviation came for wide use of a composite. The plane which does not use composites in the design now loses on start at the expense of costs, at the expense of weight, due to efficiency, fuel profitability and so on. It is possible to give an example of Boeing 787 Dreamliner, there completely composite wing. There passed information that China collected the first time a nasal part of the fuselage from a composite just about two weeks ago. At China now the situation with composites is better, than in Russia. We can try to be given up China in this plan — as replacement to America and Japan, but any design in design is already put on certain materials. Respectively, if now we change materials, at the same time we change material both on its properties, and on technology, on the producer, then it is really a difficult task, it is very fraught. And refusal of a composite in such project — his death. To create the composites... Well, of course, if now we pull hard, then five-six years are, maybe, quite real term. But here a problem in another: the spoon by a lunch is good. If this plane perspective, effective now, then in seven-eight years today's level already is outdate". But the analyst, the editor-in-chief of the Avia.ru portal Roman Gusarov says that you should not panic: Roman Gusarov the editor-in-chief of the Avia.ru portal "Everything quite is already predicted and is solvable. We were not ready to it until recently and relied on reliability of our western partners. Now it is necessary to pass certain stages of tests of domestic materials on a cycle. Everything that was made on the basis of import accessories, imported binding components, it will be necessary to make on the basis of domestic now. Yes, it can cause a certain delay in the production program of the MS-21 plane, but this problem is surmountable, still some extra time, maybe, of a year and a half order simply is required. But for
